From NCBI Gene:
Keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into epithelial keratins and hair keratins. This protein belongs to a family of keratins that are specifically expressed in the inner root sheath of hair follicles.[provided by RefSeq, Jun 2009]
Has a role in hair formation. Specific component of keratin intermediate filaments in the inner root sheath (IRS) of the hair follicle (Probable).

- Ectodermal dysplasia 7, hair/nail type
- Woolly hair, autosomal dominant
- Hypotrichosis 3
Woolly hair autosomal dominant (ADWH): A hair shaft disorder characterized by fine and tightly curled hair. Compared to normal curly hair that is observed in some populations, woolly hair grows slowly and stops growing after a few inches. Under light microscopy, woolly hair shows some structural anomalies, including trichorrhexis nodosa and tapered ends. [MIM:194300]
Hypotrichosis 3 (HYPT3): A condition characterized by the presence of less than the normal amount of hair. Affected individuals have normal hair in early childhood but experience progressive hair loss limited to the scalp beginning in the middle of the first decade and almost complete baldness by the third decade. Body hair, beard, eyebrows, axillary hair, teeth, and nails develop normally. [MIM:613981]
Ectodermal dysplasia 7, hair/nail type (ECTD7): A form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures such as hair, teeth, nails and sweat glands, with or without any additional clinical sign. Each combination of clinical features represents a different type of ectodermal dysplasia. Ectodermal dysplasia of the hair/nail type is characterized by hypotrichosis and nail dystrophy without non-ectodermal or other ectodermal manifestations. [MIM:614929]
